In vitro regeneration of plantlets was obtained from Passiflora suberosa leaf discs. Leaves from plants germinated in the greenhouse were collected and immersed in commercial sodium hypochlorite solution (3:1), during 20 minutes. Leaf discs (0.5 cm in diameter) were obtained and placed with the adaxial side in contact with the culture medium in petri dishes. Organogenesis was obtained when MS medium was supplemented with 0.5 or 1.0 mg L-1 BAP (6-benzylaminopurine), after four to eight weeks, callus proliferated from the edge of the discs. After induction, calli were transferred to modified MS media supplemented with1.0 mg L-1 GA3, under 16-hour photoperiod. Development of adventitious shoots was obtained from the callus tissues and the shoots were elongated and rooted in the same culture medium and acclimatized in the greenhouse.
